China TB/T 1979 09CuPTiRE-B Weather Resistant Steel plate Supplier 

High Quality 09CuPTiRE-B Corten steel plate is a low-alloy weathering structural steel specifically formulated with copper, chromium, nickel, and phosphorus. This composition not only enhances the plate’s atmospheric corrosion resistance but also provides superior resistance to flue gas and high-humidity environments. This composition not only enhances the plate’s atmospheric corrosion resistance but also provides superior resistance to flue gas and high-humidity environments.

What are the 09CuPTiRE-B steel plate equivalent grades?

TB/T 1979 09CuPTiRE-B is a Chinese atmospheric corrosion-resistant (weathering) steel for railway use, with equivalents often cited as Q345NQR3 (TB/T 1979) or grades sharing similar chemistry (Cu, P, Cr, Ni) and mechanicals (Yield ~345 MPa, Tensile ~480 MPa) found in standards like ASTM A588, A242, or EN 10025-5 (S355J2WP), though direct swaps need careful checks against specific property requirements for railway applications.
